All transitions have properties that you can adjust in the Transitions contextual control. Common properties are the location of the center point, the start and end values, the border, and the anti-aliasing quality setting. (For some transitions, you can also change the orientation.) The following list describes the most common controls and options you can use to adjust transition properties.
To open the Transitions contextual control, double-click the a transition in the Quick view timeline or the Expert view timeline.
Controls how the transition is aligned between clips. By default, transitions are centered between clips.
Set the percentage of the transition that is complete at the start and end of the transition.
Plays the transition backward. For example, the Clock Wipe transition plays counterclockwise.
You can change the alignment of a transition placed between two clips in the Quick view timeline or the Expert view timeline using the Transition contextual control. A transition need not be centered or strictly aligned with a cut. You can drag the transition to reposition it over a cut as desired. The Transition contextual control also contains options to specify alignment.
Whether clips have trimmed frames determines how you can align a transition between them.
In the Quick view timeline or the Expert view, position the pointer over the cut in a transition and note how the pointer changes:
If both clips contain trimmed frames at the cut, you can center the transition over the cut or align it on either side of the cut so that it either starts or ends at the cut. A clip that has not been trimmed has a rounded edge in the upper-right corner of the clip.
If neither clip contains trimmed frames, the transition automatically centers over the cut and repeats the last frame of the first clip and the first frame of the second clip to fill the transition duration. (Diagonal bars appear on transitions that use repeated frames.)
If only the first clip contains trimmed frames, the transition automatically snaps to the In point of the next clip. In this scenario, the first clip’s trimmed frames are used for the transition, and frames are not repeated in the second clip.
If only the second clip contains trimmed frames, then the transition snaps to the Out point of the first clip. In this scenario, the second clip’s trimmed frames are used for the transition, and frames are not repeated in the first clip.
You can edit a transition’s duration by dragging the end of the transition in either the Quick view timeline or the Expert view timeline. You can also use the Transition contextual control to edit the duration of a transition.
Select the transition in the Quick view timeline or the Expert view timeline and do one of the following:
Position the pointer over the end of the transition until the Trim‑In icon or the Trim‑Out icon appears. Drag the Trim‑In icon or the Trim‑Out icon to the left or right to adjust the duration.
Double-click the transition and radjust the duration using the Transition contextual control.
note: Lengthening a transition’s duration requires that one or both clips have enough trimmed frames to accommodate a longer transition.
The default duration for transitions is initially set to 30 frames for video and 1 second for audio. You can change the default duration to a value that better suits your movies. Although the new setting has no effect on transitions already placed in the movie, all transitions you subsequently place will default to this value.
To copy and paste transitions, select consecutive clips that have a transition before selecting the transition you want to copy.
Video transitions are pasted to video tracks and audio transitions are pasted to audio tracks.
